Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Gastrointestinal Symptom Responsiveness Scale (GSRS) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    The GSRS is a measure of gastrointestinal symptoms. It includes 15 questions, rated on a Likert scale of 1-7, from no symptoms to severe symptoms, respectively (i.e., higher is worse). We report an average score for all 15 questions, so the possible range for the average score is also 1-7.


Secondary Outcome Measures :
  1. Parent Global Impressions-Revised (PGI-R) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    The PGI-R is a rating of change of 18 autism symptoms compared to baseline, with each symptom rated on a Likert scale from -3 (much worse) to zero (no change) to +3 (much better). We report the average change of the 18 symptoms, so the possible range is from -3 to +3.

  2. Blood Safety Markers (Assessment of Blood Chemistry Panel and Complete Blood Count) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    Number of participants who had a clinically significant change in their blood safety markers (comprehensive metabolic panel including kidney/liver function and complete blood count with differential)

  3. Childhood Autism Rating Scale (CARS) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    The CARS is an assessment of 15 autism-related symptoms. Each item is scored on a scale of 1 (no symptoms) to 4 (severe symptoms), and the scores for each symptom are summed to obtain a total score. So, the possible scores range from 15 to 60, with a higher score indicating greater severity.

  4. Social Responsiveness Scale (SRS) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    The SRS is an assessment of social skills based on 65 items, where each item is scored on a range of 0 (no symptoms) to 3 (severe symptoms). The total score is a sum of the individual scores, so the total possible range is from 0 to 195, with a higher score indicating greater severity of symptoms.

  5. Short Sensory Profile [ Time Frame: baseline and 10 weeks ]

    The Short Sensory Profile is an assessment of sensory problems.

    However, the data on this scale was not collected due to administrative error.


  6. Vineland Adaptive Behavior Scale (VABS) [ Time Frame: baseline and 18 weeks (8 weeks after treatment stopped) ]
    The VABS is an assessment of adaptive behaviors, and we analyzed it to determine the developmental age of the participants, with possible scores ranging from 0 years to 21 years.

  7. Daily Stool Record (DSR) [ Time Frame: Baseline and 10 weeks (end of treatment) ]
    The DSR is a record of the type of stool that a participant had each day, using the Bristol Stool Form which ranges from 1 (very hard) to 7 (liquid). We then analyzed the data as % days of abnormal stools over a 14 day period, where an abnormal stool is defined as an unusually hard stool (types 1-2), unusually soft stool (types 6-7), or no stool that day. So, the possible range of % days of abnormal stools is from 0% to 100%, with a higher score indicating a more severe problem.
